When tissue forms on the right ventricular septal surface (often thought to be tricuspid valvular in origin), it is termed an aneurysm of the membranous septum. (medscape.com)
Normal closure of the ventricular septum occurs through multiple concurrent embryologic mechanisms that help to close the septum's membranous portion: (1) downward growth of the conotruncal ridges forming the outlet septum, (2) growth of the endocardial cushions forming the inlet septum, and (3) growth of the muscular septum forming the apical and midmuscular portions of the septum. (medscape.com)
Ventricular septal defects (VSDs) occur when any portion of the ventricular septum does not correctly form or if any of components do not appropriately grow together. (medscape.com)
